QAIPM-2012-Ch-1634: NEET 2012 Chemistry - Class 11 AIPM-2012-Ch-1634 Solution: Given that the equilibrium constant for the reaction \(2SO_2(g) …

Given that the equilibrium constant for the reaction 2SO2(g)+O2(g)⇌2SO3(g)2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature? SO3(g)⇌SO2(g)+12O2(g)SO_3(g) \rightleftharpoons SO_2(g) + \frac{1}{2}O_2(g) 1.8×10−31.8 \times 10^{-3} 3.6×10−33.6 \times 10^{-3} 6.0×10−26.0 \times 10^{-2} 1.3×10−51.3 \times 10^{-5}

Multiple Choice Options

  • A 1.8 ×\times _ 10 −- _ 3
  • B 3.6 ×\times _ 10 −- _ 3
  • C 6.0 ×\times _ 10 −- _ 2
  • D 1.3 ×\times _ 10 −- _ 5

Step-by-Step Verified Solution

2SO 2(g) + O 2(g) _ 2SO 3(g) ,    K SO 3(g) _ SO 2(g) + 1 2 O 2(g) ,     K' = 1 K _ K' = 1 278 = 6.0 _ 10 _ 2
